3. Airdolphin Features
3-1 10 State-of-the-Art Technologies
u
Extremely Low Mass
The total weight of the Airdolphin is only 17.5kg. This means it weighs just 17.5g.per generated
watt (when the continuous rated output is 1kW). Thus, the Airdolphin tracks wind better in turbulent
flows, resulting in more efficient power generation. The light weight also allows the unit to be installed in a
wide variety of places.
u
Newly-Designed Rudder
The rudder of the Airdolphin uses the newly-developed Swing Rudder System. This system ensures the tur-
bine’s superior response to sudden changes in the direction of wind, improving the efficiency of power genera-
tion.
u
Newly-Designed Rotor
The Airdolphin comes with a new rotor system consisting of:
(1) Three ultra low-mass blades, reinforced by a carbon-fiber skin for superior rigidity. () A hub mechanism
that uses the newly-developed Multi-Stagger System (incorporating multiple airfoils and lift angles). This
technology allows the turbine to capture the wind effectively and respond flexibly to changing conditions, from
slight to stormy winds, eliminating the need for pitch controls.
u
An Innovation for Low Noise Newly-Designed Rotor
The Airdolphin comes with the “Noise Disrupter Coating”. This new blades have a number of thin ridges
applied on its surface, which significantly reduces air flow noise. Our designers were inspired by the wings of
owls that enables it to fly almost silently and unnoticed while approaching its prey.
u
Robust Body Structure
Bolt-less self-fitting body inspired by Japanese traditional block puzzle craftsmanship. This technique ensures
an exact fit and provides superb resistance to adverse weather conditions, greatly minimizing maintenance
requirements.
u
Power-Assist Function
For 10 seconds every minute when there is no wind, the Airdolphin uses previously- generated power to spin
the rotor. This allows the rotor to reach the cut-in point more quickly--even when there is near zero wind,
allowing the unit to capture the wind effectively. The Power Assist Function also prevents freezing of the rotor
due to low temperatures.
